[0033] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0035] like Figures 1 to 4 As shown, an embodiment of the present application provides a battery fuse box, including a bottom shell 1, on which a first connector 2, a second connector 3, a first wiring port 4, a second wiring port 5, a first fuse 6, and a second fuse 7 are provided. The first fuse 6 is connected between the first connector 2 and the first wiring port 4, and the first connector 2 and the first wiring port 4 are conductively connected through the first fuse 6. The second fuse 7 is connected between the second connector 3 and the second wiring port 5, and the second connector 3 and the second wiring port 5 are conductively connected through the second fuse 7. The first connector 2 is used to connect to the first power supply, and the second connector 3 is used to connect to the second power supply.

[0036] like Figure 1 As shown, the first fuse 6 and the second fuse 7 may be bolt-type fuses, the first power supply may be a battery, and the second power supply may be a DCDC power supply, a DCDC (Direct Current) power supply, or a DC-to-DC power supply.

[0037] In the battery fuse box provided in the embodiment of the present application, after the electric component is connected to the first wiring port 4, the current of the first power supply is input to the electric component through the first fuse 6, and the first fuse 6 protects the circuit between the first power supply and the electric component. After the electric component is connected to the second wiring port 5, the current of the second power supply is input to the electric component through the second fuse 7, and the second fuse 7 protects the circuit between the second power supply and the electric component. One battery fuse box can realize the circuit protection of the first power supply and the second power supply, with low cost, small space occupation and simplified circuit arrangement.

[0038] The first connector 2 is a fixed post, which is fastened and locked on the positive post of the battery by a fastener, and the first connector 2 is conductively connected to the positive pole of the battery. In specific implementation, the first connector 2 includes an open circular ring and a connecting piece connected to each other, and the open circular ring is sleeved on the positive pole. The size of the open circular ring can be adjusted to lock on the positive pole, and can be adapted to positive poles of different sizes. The connecting piece and the copper sheet at one end of the first fuse 6 are stacked and distributed, and the connecting piece and the copper sheet at one end of the first fuse 6 are crimped together by a fastener, and the copper sheet and the connecting piece are in contact and conductive, and the fastener locks the connecting piece and the copper sheet at one end of the first fuse 6.

[0039] The first wiring port 4 includes a copper sheet and a fastener inserted through the copper sheet. The copper sheet at the other end of the first fuse 6 is stacked with the copper sheet of the first wiring port 4. The fastener locks and presses the copper sheet at the other end of the first fuse 6 and the copper sheet of the first wiring port 4 together to make the copper sheet at the other end of the first fuse 6 conductively connected to the copper sheet of the first wiring port 4.

[0040] The second connector 3 includes a copper sheet and a fastener passing through the copper sheet. When the connecting sheet of the second power supply is connected to the second connector 3, the connecting sheet of the second power supply is stacked with the copper sheet of the second connector 3. The fastener locks the copper sheet of the second connector 3 and the connecting sheet of the second power supply together, so that the connecting sheet of the second power supply and the copper sheet of the second connector 3 are conductively connected.

[0041] Similarly, the second wiring port 5 includes a copper sheet and a fastener inserted through the copper sheet. The copper sheet at one end of the second fuse 7 is stacked with the copper sheet of the second wiring port 5. The fastener locks and presses the copper sheet at one end of the second fuse 7 and the copper sheet of the second wiring port 5 together to make the copper sheet at one end of the second fuse 7 conductively connected to the copper sheet of the second wiring port 5.

[0042] like Figure 4 As shown, in order to install the bottom shell 1 on the battery box 30 and the space for accommodating the fuse box is limited, in some embodiments, the bottom shell 1 includes a first shell 11 and a second shell 12 intersecting in an L shape, and the first shell 11 is connected to the second shell 12. The top surface of the battery box 30 contacts the first shell 11, and the side surface of the battery box 30 contacts the second shell 12, and the battery box 30 supports the bottom shell 1.

[0043] Since the first fuse 6 and the second fuse 7 are standard parts, the length of the first fuse 6 and the second fuse 7 cannot meet the distance between the first wiring port 4 and the first joint 2, and the first fuse 6 and the second fuse 7 cannot be bent, and the conductive connection path between the first wiring port 4 and the first joint 2 on the bottom shell 1 is usually not a straight path. The conductive connection path refers to the current path that can conductively connect the first joint 2 and the first wiring port 4. Figure 1As shown, the conductive connection path between the first wiring port 4 and the first connector 2 is a bending type. Therefore, in some embodiments, the bottom shell 1 is further provided with a first conductive sheet 8 and a second conductive sheet 9, the first conductive sheet 8 is connected between the first connector 2 and the first fuse 6, and the second conductive sheet 9 is connected between the second connector 3 and the second fuse 7. The first conductive sheet 8 can be bent, and the first conductive sheet 8 can make up for the length of the first fuse 6 being less than the path distance between the first wiring port 4 and the first connector 2, and the second conductive sheet 9 can make up for the length of the second fuse 7 being less than the path distance between the second wiring port 5 and the second connector 3.

[0044] The first conductive sheet 8 is stacked with the connecting sheet of the first joint 2, and the first conductive sheet 8 and the connecting sheet of the first joint 2 are pressed and connected together by fasteners. The first conductive sheet 8 is stacked with the copper sheet at the other end of the first fuse 6, and the first conductive sheet 8 and the copper sheet at the other end of the first fuse 6 are pressed and connected together by fasteners. The second conductive sheet 9 is stacked with the copper sheet of the second joint 3, and the second conductive sheet 9 and the copper sheet of the second joint 3 are pressed and connected together by fasteners. The second conductive sheet 9 is stacked with the copper sheet at the other end of the second fuse 7, and the second conductive sheet 9 and the copper sheet at the other end of the second fuse 7 are pressed and connected together by fasteners.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments, the first wiring port 4 includes a plurality of first sub-wiring ports 41, and the plurality of first sub-wiring ports 41 are distributed at intervals. Exemplarily, the plurality of first sub-wiring ports 41 are distributed at intervals side by side. A plurality of first fuses 6 are provided, and the plurality of first sub-wiring ports 41 are connected one-to-one with the plurality of first fuses 6. Each first fuse 6 is connected between the first conductive sheet 8 and a first sub-wiring port 41. The connection area of ​​the first conductive sheet 8 is larger than the connection area of ​​the connection sheet of the first connector 2, and the first conductive sheet 8 can be connected to the plurality of first fuses 6. The plurality of first sub-wiring ports 41 meet the power distribution requirements of the first power supply for the plurality of electrical components.

[0046] Considering that the rated currents of the wires of multiple electrical components are different, in some embodiments, the capacities of at least two first fuses 6 are different from each other to meet the use requirements of multiple electrical components with different rated currents. The capacity of the first fuse 6 refers to the maximum current value that the fuse can withstand. The rated current of the wire of the electrical component corresponds to the capacity of the first fuse 6. The first fuse 6 protects the power distribution circuit of the electrical component with the first power supply. At the same time, for the same electrical component of different models, the rated current of its wire is also different. Therefore, multiple first wiring ports 4 connected to multiple fuses with different capacities can meet the needs of different models. In other words, the battery fuse box is suitable for vehicles of different models and has good application prospects.

[0047] In some embodiments, the second wiring port 5 includes a plurality of second sub-wiring ports 51, the plurality of second sub-wiring ports 51 are spaced apart, the plurality of second sub-wiring ports 51 are connected one-to-one with the plurality of second fuses 7, the capacities of at least two second fuses 7 are different from each other, and each second fuse 7 is connected between the second conductive sheet 9 and a second sub-wiring port 51. The plurality of second sub-wiring ports 51 meet the power distribution requirements of the second power supply for a plurality of electrical components. The capacities of at least two second fuses 7 are different from each other, meeting the power distribution requirements of the second power supply for a plurality of electrical components with different rated currents.

[0048] In some embodiments, Figures 1 to 4 As shown, the first connector 2 is located in the first shell 11, and the plurality of first sub-connection ports 41 are located in the second shell 12. The first conductive sheet 8 includes a first conductive sheet 81 and a second conductive sheet 82 intersecting in an L shape. The first conductive sheet 81 and the second conductive sheet 82 are an integrally formed structure. The first conductive sheet 81 is located in the first shell 11 and is connected to the first connector 2. The second conductive sheet 82 is located in the second shell 12 and is connected to the plurality of first sub-connection ports 41. The bending of the first conductive sheet 8 is achieved. Since the first connector 2 needs to be connected to the pole of the battery box 30, and the space on the battery box 30 near the pole that can accommodate the first shell 11 is limited, and the side of the battery box 30 can accommodate the second shell 12. The space is sufficient, so the plurality of first sub-connection ports 41 are located in the second shell 12. At the same time, the side space of the battery box 30 can be used for the wires of the electrical components to be connected to the first sub-connection ports 41.

[0049] In some embodiments, Figure 1 As shown, the second connector 3 , the plurality of second sub-connection ports 51 and the second conductive sheet 9 are all located in the second housing 12 .

[0050] In some embodiments, a third wiring port 10 and a third conductive sheet 101 are further provided on the first shell 11. The third conductive sheet 101 is connected to the second conductive sheet 9. The third conductive sheet 101 and the second conductive sheet 9 can be an integrally formed structure. A third fuse 102 is connected between the third conductive sheet 101 and the third wiring port 10.

[0051] The first fuse 6 and the second fuse 7 can adopt MIDI insurance, and the capacity range of MIDI insurance is 30A-200A. The capacity of the first fuse 6 and the second fuse 7 can be 30A, 60A, 100A, 140A, 180A and 200A. The third fuse 102 can adopt MEGA insurance, and the capacity range of MEGA insurance is 40A-500A. The capacity range of the third fuse 102 can be 40A, 80A, 140A, 240A, 280A, 340A, 420A, 480A and 50A. The capacity of the third fuse 102 is much higher than that of the first fuse 6, and can be used for electrical components with large rated current. The third wiring port 10 connected to the third fuse 102 is arranged on the first shell 11, which is convenient for distinguishing the third wiring port 10 from the first wiring port 4 and the second wiring port 5, and is convenient for users to confirm. At the same time, the use space of the bottom shell 1 and its surrounding space can also be reasonably utilized, such as Figure 1 and Figure 2 As shown, the electrical components connected to the third wiring port 10 and the electrical components connected to the second wiring port 5 are respectively located on two sides of the bottom case 1 .

[0052] In some embodiments, the battery fuse box further comprises a cover body which covers the bottom shell 1 , and the cover body protects the above-mentioned components arranged on the bottom shell 1 , and words or symbols for instructions may also be engraved on the cover body.

[0053] Furthermore, the cover body includes a first cover body 201, a second cover body 202, and a bending portion 203 connected between the first cover body 201 and the second cover body 202. The first cover body 201 is used to cover the first shell 11, and the second cover body 202 is used to cover the second shell 12. The first cover body 201 is detachably connected to the first shell 11 through a buckle, and the second cover body 202 is detachably connected to the second shell 12 through a buckle.

[0054] The first cover 201 is made of hard plastic, and the second cover 202 is made of soft plastic. The first cover 201 can be rotated relative to the second cover 202 through the bending portion 203, so that the first cover 201 can be opened separately, which is convenient for users to check or disassemble the components on the first shell 11. Of course, the second cover 202 can also be opened separately, which is convenient for users to check or disassemble the components on the second shell 12. At the same time, compared with the situation where the first cover 201 and the second cover 202 are a common part and can only be opened together, the first cover 201 and the second cover 202 set above can open the first cover 201 first, and then open the second cover 202, which reduces the difficulty of installing and disassembling the cover and the bottom shell 1.

[0055] Another embodiment of the present application provides a vehicle, such as Figure 4As shown, it includes a battery fuse box and a battery box 30, the battery box 30 has a positive electrode post, and the first connector 2 is connected to the positive electrode post.
